The Pacific Northwest has been quiet over the past few weeks, but a new tremor cluster has been growing since the final days of August.
Here is the map for yesterday; just over 34 hours and 630 epicenters.
And this is the map for the past 6 days, with over 150 hours of slow slip.

I'm not certain that this is the beginning of the tremor episode for this year, which is anticipated to begin anytime during the late summer/fall
timeframe. But I don't think this is the traditional location. The PNSN has a tremor
set up for this years' event; I'm waiting for an update to be posted there.
On a related topic, the ETS spectrograms found here
haven't been updated since
Mr. Vidale, will they be coming back?
I don't think that the CSZ is "ready to rupture" today as this thread title suggests; rather this seems to be the thread that is most often used for
posting seismic information for the PNW region.
Although, the scientists studying ETS/'slow slip' do suggest that these episodes can slightly raise the chances of a major rupture.
